421 4.2.0 sender rejected AUP#SNDR
I manage a few mail servers for my employer. We noticed that we are being blocked by T-Mobile (relay=tmo-east.mx.a.cloudfilter.net). We send a lot of messages to our customers' SMS gateway addresses ...
For any others hampered by the random delays of home automation messages sent via your phonenumber@tmomail.net, I have written an AppleScript that can send either SMS (if your phone is on your WiFi) or iMessage (if you're not on the same WiFi as the computer sending the text). The messages get through without the random delay caused by the spam filtering and I don't *think* it's subject to getting blocked.
The only problem is that it kind of defeats the purpose of wanting to send an SMS (if you don’t have a data signal), but I learned on Reddit that soon all calls and SMS messages will require a data connection anyway due to the decommissioning of the 2G network.
DM me if you'd like the script. I'll probably blog it eventually.
